📋 Teacher notes

•vx is constant throughout — no horizontal force acts on the projectile.
•When h₀ > 0, the optimal angle for max range drops below 45°.
•Complementary angles give equal range only when launched from ground level.
•Platform height slider — drag it up to simulate a cliff or tall building.
•Use the gravity slider to explore projectile behaviour on the Moon (1.6 m/s²) or Mars (3.7 m/s²).
